In the 20th century, the national liberation movement against imperialism and colonialism became a world-wide movement in many colonial countries (Smith, Anthony. 2010. pp. 9, 25–30). Each country-nation has mirrored in one way or another depending on historical and socio-political conditions, especially the leaders' way (Finlayson, Alan. 2014). Under British colonial rule, the nationalist movement in India was run under the leadership of patriotic and nationalistic leaders such as “a great soul” Mahatma Gandhi (McGregor, Ronald Stuart.1993, p.799) , Rash Behari Bose, Jawaharhlal Nehru, and “a respected leader” Netaji Subhas Chandra Bose (Gordon, Leonard A. 1990, pp. 459–460) ... Among them, Netaji Subhas Chandra Bose has emerged as great leader. The paper consists of an introduction, = three sections and conclusion: 1.
